I have a system that uses HC-SR04s to monitor the queue of the lunch room at our school. It's really straightforward and works rather nicely, writing the data to a web server every minute or so. I see the normal operation as this:
Code: Select all
[0;32mI (87533883) wifi: event 4[0m
[0;32mI (87534973) event: ip: 192.168.0.190, mask: 255.255.255.0, gw: 192.168.0.1[0m

S1:34 S2:34 S3:56

H1: 9 H2: 9 H3: 0

But as I watch the operation, stuff like this in the monitor:
Code: Select all
I (87122163) wifi: n:7 2, o:7 0, ap:255 255, sta:7 2, prof:1
Code: Select all

Many thanks!
